Intel Prescott chips not backward compatible with current motherboards

[Qba73]

Aint this just a kick in the A@@, now i know the later chips will use socket 775, but the inital prescott's will use 478 but will still be uncompatible with our boards..

lol... I posted this in the Mobo section too..:p

Time for some new motherboards. . . .



:p

No surprise here. Buy an Intel cpu, you gotta buy an Intel (chipset) motherboard. Just the way it's been, and the way it will always be. :)

But even the 865/75 will not support the new chip...

With a new revision I'm sure they will. Just as the i815 was revved to support Tualatin (A-step vs. B-step).

Yeah, but which means the mobos we have right now based on the 865/75 will not work...:(

Yup. Unless there is a similar trick that was possible with the Tualatin CPUs on the A-step of the i815 chipset. I know from experience to never underestimate the ability of tweakers and the like.

It all depends on what the incompatibility is because of. Too little information is available today to give a certain verdict.

i say skip the 478 prescotts and wait for the 775 prescotts when you want to upgrade i mean it will only be like 4months after the 478 prescotts come out that the 775 prescotts will debut. i think intel is really shooting the 478 prescott in the foot.

[Chuck232]

I agree Qba73. I mean how many 478 Prescott CPUs are they gonna sell if the socket 478 Prescotts indeed need a new mobo and then the 478 socket goes no further than ~3.4GHz...:rolleyes:

EDIT: Just remembered probably to people like me who bought the 1.4GHz Willamette socket 423 from Dell.:p :eek:

new info... new chipset... power hog...

why worry about backward incompatibility? dont we change our mobo and processors more often than we buy new pair of socks or underwears? :)

[ThugsRook]

@ 100w, i dont think youll have to worry about any compatability.

[Jojo1971]

100W:eyepop: :eyepop: :eyepop: ---> new processor + new mobo + new prommy or watercooling setup :(

[ThugsRook]

in case ppl dont realize how hot 100w is.....

its hotter then what us OCers are running @ right now :eek2:

[Duvie]

Thugs...Why is this??? I mean we are only jumping 200mhz, lower vcore likely with the lowering of the miccon size..so why the big jump in heat???:wave:

[ThugsRook]

i donno Duvie.
maybe one of those "not speaking for intel" guys could shed more light on this ;)

sounds like a Willamette to me :eek2:

[Jim]

Prescott does have high dissipation and that 100 watts was close to that number, while Intel is already working on a new core revision that could cut this dissipation.

Hopefully they can cool that puppy off a bit before it's released. :(

[mysteryman]

how hot is 100W? lick your finger and stick it on a 100W light
bulb that's been on for an hour! :cry:

doubling the cache size pretty much will come close to doubling
the power... on most microprocessors, the cache arrays consume
about 50-75% of all power. What was the power of the 3.0C?

article didn't say what frequency they were running either

process shrink - less power
cache double - more power
frequency higher - more power
voltage drop - less power

perhaps there is more leakage current with the shorter
lengths...

Not likely (but who knows). It's more likely that there will be a new stepping in 1H04 before the new 775(?) pin prescott's are released.

that is the way I was looking at it as well...I wonder if they include HT operations now when they figiure these numbers. I use to here that HT enbled often would raise heat at even default vcore and default speeds...

gee ~ i hope the new DDR2 moboards will support 191fsb :lol:

Well, the bus is going to be 266Mhz (AFAIK) so...I don't think there'll be a problem :-)
